As

will be readily understood, when the tape is disposed bctwecnthe rollers 9 and 15"and the nlotor 13 is in operation'the tape will be moved longitudinally through the instrument.

'lhe' pen 93 may be of any suitable construction and is preferably supplied with in]:

An eIectrO-magnet-"ZT issuitablysecnred to the ,liase 1 and adapted to receive current impulses from any suitable source, the binding 1 posts 28 being mountednon the base 1 to which thecurrent-bearing Wires may be ses a dj'ustably mounted in an arm 7 the cores 31 of should be apparent without further descripthrough ing from the tion of the structure 12 of the motor 13 rotates the roller 9, cooperating with the roller 1.5, draws the tape the instrument at a constant speed and the pen 23 resting on the tape will mark a straight line 'thereon which is substantially parallel with one of the edges of the tape As each current impulse is received by the electro-magnet 27 the armature 29 will be attracted'and drawn toward the electro-magnet 27, carrying with it the yoke 34 and hence moving the tape laterally. The result will be that with each pulse the normally straight line will be broken and a'series of markings, such as indicated in Fig. 1, will appear on the tape indicating the duration of the current impulses and herebynindicating to persons familiar with the code the ideas which are being telegraphically transmitted and received by the instrument.

It will be readily understood-fromthe foregoing that I have succeeded in perfecting a recorder which eliminates completely the necessity for providing a moving or a balanced pen and that consequently the disadvantages of such; structures as known in have been entirely overcome.

My recorder is extremely simple in construction and will operate efficiently for long periods without attention or adjustment other than the replacement of the tape as the roll becomes ,exhausted.

It will be obvious that various changes may be'made in the form, construction an arrangement of the parts without departspirit and scope of the invention or sacrificing any of its material advantages, the form hereinbefore described being merely a preferred embodiment thereof.
